Subject: Compaction Report
Kaiser Carlsbad Medical Office Building – Parking Structure Remodel
6860 Avenida Encinas
Carlsbad, CA 92011
Project Number: W6413/CAP013486
A series of in place density (compaction) tests were taken within the subject site at the locations listed herein from March
29, 2019 to June 5, 2019.
Field testing of the soil and base was by the direct transmission nuclear method, ASTM D6938. The maximum density -
optimum moisture relationship was established in the laboratory by the ASTM D1557 test method. Field density tests
were performed in conformance with previously submitted recommendations provided in the “Preliminary Soil
Infiltration Testing and Pavement Structural Section Report” dated May 10, 2017, RMA Job No. 17-0497.
A summary of the results of all tests performed is attached. The field density tests were taken at locations selected by
our representative and do not constitute certification of compaction of the subject improvements. We have performed
the tests, as previously described, in accordance to generally accepted soil testing practices. No other warranty, express
or implied, is made.
